Flask Project


In the quilt dashboard, we used the flask language. I have created the sample project to learn the flask, Django and sqlalchemy .



I used a postman to insert the data into the database. I also attached the link.

What is Postman?

Postman is currently one of the most popular tools used in API testing. It started in 2012 as a side project by Abhinav Asthana to simplify API workflow in testing and development. API stands for Application Programming Interface which allows software applications to communicate with each other via API calls.




Interfacing BO Motor with Arduino

~ Vimal, Abilash, Prabha

We had learnt to interface a toy DC motor with the arduino platform. The idea is to design a sensor controlled vehicle which navigates based on the intensity of the light which falls on it.

We used a LDR(Light Dependent Resistor) as a sensor element for the project. The analog value of intensity of the light falling on it is measured and it ranges from 0 – 1024 (10 bit resolution limitation of arduino). We used a dual H bridge IC named L293D to actuate the motor. To get the desired torque, we have selected a geared motor with 300 RPM @ 12VDC.

For this task we used only one geared motor and one half of the dual H Bridge. For initial prototyping we used the breadboard, the enable pin of one half of the IC is connected to 5VDC, two IOs are assigned namely 4 and 7 to control the outputs of the IC. The LDR is connected to the analog pin A0. The LDR circuit is designed as a voltage divider circuit. The analog value obtained from the task is compared continuosly with the threshold limit of 950. If the value is changed the motor will rotate in clockwise direction else in anticlockwise direction.

STEM land meeting

~Poovizhi, Abilash

Yesterday we had STEM land meeting with all the coordinators of different STEM land and STEM land math teachers. Sundar presented a scratch program for fraction. Later we were all given small booklets by Azim Premji University on each topic like Addition, subtraction, multiplication, measurement. It had different activities that could be done with children in learning the concept. We agreed to read the booklet and present what we learnt from it make a model of it and present it to others in the next session. For some time we all read our booklet in silence and took notes.

Then shared about cyclic number which he read from his book which was new and interesting for all of us. The cyclic number is the following

1/7 = 0.142857

142857 x 2 = 285714

142857 x 3 = 428571

142857 x 4 = 571428

142857 x 5 = 714285

142857 x 6 = 857142

142857 x 7 = 999999

And the other one was to find the pattern and come up with an equation

1 = 1

3+5 = 8

7+9+11 = 27

What is the pattern and will the next line be?

1       = 1       : 1^3

3+5       = 8      : 2^3

7+9+11      = 27   : 3^3

13+ 15+17+19  = 64   : 4^3

n(n-1)+1 is the equation

10-day Vipassana course Experience

~ Ranjith, Sivaraman, Vasanth

We were participated in a 10-day Vipassana course. we found it useful in various ways.


In my first 10-day Vipassana course, I develop ability of tolerance to face problems in life. But I realize that ability of tolerance is not enough, because most of time I felt “I am submissive or aggressive“ when I face a problems, which leads me to question myself  about “my ability of metacognition”. So I decide to go another 10-day vipassana course with a goal in mind to improve my metacognition ability.

Three things that I got from vipassana meditation through experience (Bhavanamaya panya):

  1. When I push my mind out its comfort zone (ex: sitting for an hour without moving) for an hour, made me realize that, I have ability to adapt my body and mind to the situations.
  2. I had lot of thought about misery in the past, during mediation. After some time realize that “source of all my misery is an attachment towards my ego and my expectation”.
  3. Awareness of sensation, and ability to think “why and how certain thought are originated in my mind and how to control it”.

~ vasanth:

It was a great experience for me at Vipassana. There I learned to be aware of my sensations and to maintain equanimity. To be in equanimity I came to know that I should avoid craving and aversion. Because craving and aversion lead to misery in life. For this, I have to accept the joy and sorrow equally. And also I learned to get relief from my mental stress and to sharpen my concentration and focus.

There were three stages such as Anapana, Vipassana and Metta. In Anapana I was asked to observe my breath which moves in and out of my nostrils and to notice the places where the fresh air touched the inner walls of my nostrils for the first two days then on the third day I started to be aware of the sensation of my nose. Then, on the next day onwards I started to abserve the sensations in my body, from head to feet. As I kept my complete attention on my sensations throughout the body, my concentration was not distracted by anything. This made me to be away from craving and aversion.

On the nineth and the tenth day I learnt Metta, which taught me to share my love, compassion, kindness, peace, harmony and goodwill to all human and non-human beings.

~ R.Sivaraman:

The schooling for the mind to see things as they really are, the name is Vipassana. One of India’s most ancient techniques of meditation. It was rediscovered by Gotama Buddha.

it’s a 10-day course given for free from Dhamma , for Dhamma to make everyone practice and get liberated. By Dhamma’s servers to help others to practice dhamma peacefully.

This course makes people feel the sensations, realize not to react blindly and just let pass slowly, slowly Anicha Anicha. we only react to our sensations good or bad, nothing out is making a sensation in us, its our own craving and clingings

Liberation, the word itself opens up the door to internal peace .no craving, no clinging and no madness only sensations and let them pass slowly, slowly.

Mental practice to come out of all our reactions and make us aware of our reactions and madness.

The art of living a liberated and peaceful life while sharing compassionate love and peace for everyone.

Solving 4×4 Rubik’s cube

~Saranya, Arun

Most of the children who come to STEMland can solve 3×3 Rubik’s cube.

What’s next??

We now have bought 4×4 Rubik’s cube and this made a few of the students curious. Now 3 children from class 7, 8 and 9 can solve 4×4 cube. This only took them for about 3 weeks to figure out how to solve it.

Following is a video of a child (padmanaban) from 7th grade solving 4×4 cube. He solved it under 2 minutes.
